与人为强迫引起的全球变暖相比,末次间冰期是轨道强迫引起的过去80万年来最暖的一个间冰期,但鲜有人研究末次间冰期中北非季风的响应.因此,本文基于CMIP6多模式模拟结果对比研究了末次间冰期和SSP5-8.5情景下北非季风的响应,发现末次间冰期下北非季风平均降水及其降水变率均远大于SSP5-8.5情景下的结果.轨道强迫导致的北大西洋暖于南大西洋增加了北非季风环流和平均降水,同时,南北大西洋海温梯度变化通过增强热带北大西洋的海气相互作用增大了海温梯度和撒哈拉低压的变率,从而增强了北非季风降水变率.

In recent years, the transmission rate of mobile network becomes insufficient to serve numerous mobile users. Relay technique has been proposed to improve the data rate of mobile networks for many years. In the paper, the planning problem of heterogeneous cellular network is defined and limited in two-hop relaying. The defined problem aims to tackle with three objective functions at the same time. A meta-heuristic planning algorithm is proposed based on Ant Colony Optimization (ACO) algorithm. The proposed ACO-based algorithm optimizes the placement results of macrocells, microcells and femtocells. In the simulation-based result and analysis, the ACO-based algorithm yields the higher capacity and more covered users with the lowest construction cost compared to the two heuristic algorithms, i.e., Top-Down and Bottom-Up algorithms. © Springer Nature Singapore Pte Ltd. 2020.

Understanding the research landscape of any domain is of primary importance at all stages of a concept's evolution. Research in the domain of analytics has increased exponentially in the past decade, analytics is a tool being applied to increase effectiveness and efficiency within all domains. Similarly, there are numerous research studies that have applied analytics to the domain of higher education. Assessing research activity is important for planning future research and identifying the way forward to make meaningful contributions. The objective of this paper is to examine the current research in this domain and to identify emerging areas of research to make meaningful contributions. Bibliometric analysis was applied using Scopus. Documents on analytics and higher education keywords in business, accounting and management and published in journals were considered for the analysis. Vos Viewer was used for bibliometric analysis in the area, to identify emerging research themes and to understand the scope of applying analytics in higher education. The search query found 1635 documents when using the keywords of 'analytics' and 'higher education'. This was further narrowed down to research in Business Management and Accounting and using Journal articles and conference articles, finally yielding 103 articles. After a primary read to remove articles misplaced in the group the final number of articles include for the bibliometric analysis came down to 98. There has been an increase in publications since 2018 with interest increasing post pandemic in the area. The research categories are Student outcomes and perspective, academician outcomes and perspective, design of learning systems, etc. Based on this, it is recommended that research should focus on theoretical aspects of applying analytics to HEIs, ethical issues in data collection, etc.. © 2022 IEEE.

Significant privacy and security concerns apply to the Internet of Things. IoT issues might include driver ignorance, inadequate device updates, a lack of robust and effective safeguards, and unreliable dynamic instrument management. The study's objectives include identifying (a) various cybersecurity concern regarding, (b) techniques for attempting to secure IoT-enabled options and buildings, (c) available at the moment security remedies, and (d) the much more acceptable privacy depictions for the differing stages of technology apps. Researchers proposed a new, generally expanded layered paradigm that included security and privacy tools as well as layer documenting. the recommended virtualized Internet of Things system's deployment and evaluation. Internet of Things (IoT) units built as virtualized using Amazon Web Services make the bottom layer (AWS). The topcoat was developed by researchers utilising AWS's cloud-based IoT platform (the cloud). To allow data transfer between the envisioned cloud/edge authorised IoT representation's levels, researchers have created ssl certificates. © 2022 IEEE.
